Scale-dependent rotating BTZ black hole

Understand

This work presents a generalization of the rotating black hole in two plus one dimensions, in the light of scale--dependent gravitational couplings.

• In particular, the gravitational coupling $\kappa_0$ and the cosmological term $\Lambda_0$ are not forced to be constants anymore.
• Instead, $\kappa$ and $\Lambda$ are allowed to change along the radial scale $r$.
• The effective Einstein field equations of this problem are solved by assuming static rotational symmetry and by maintaining the usual structure of the line element.
